CUT ING Ann WELDING 'roncnf 1" To all wk-m itmayconcern f Be it known that I, CHAnLns' FjHnMMnn,

a citizen of the United States", residing in the borough of Roselle Park, inthe county of Union and State of New Jersey,havei 'in-i vented certain; new and useful' Improve-; m'ents in Cutting and Welding Torches, of;

which the following is a full, clear, ai d exact description, such as will enableothersskilled' inthe art to which it pertains to make-con} struct, and use the same,- referencebeinghad tojthe accompanying drawingsiand to t'h e" reference characters marked thereon. This invention relates combustion for conveying'the gases to the nozzle, and. to simplify the structure of the torch, so as to render the same positive yet effective in operation, simple andinjexp ensive in construction anddurablein use.

These objects I perform in'the 'preferred embodiment of my invention, which Iv have illustrated in the accompanying drawings,

7 scale, a transverse sectional view taken on.

looklng 1n the direction to which reference is had and in which similar reference characters indicate correspond ing parts in the several views.

In the drawings, Figure 1 represents, a side elevation of my improved device insection. V

Fig. 2 represents, the same in elevation. Fig. 3 represents, onan enlarged scale, a detailed view of the-disk; and

Fig. 4; represents, also on an enlarged line 00-m of Fig. 1, indicated by the arrow.

In the drawings, 1 designates a chambered torch head or nozzle, one end of which is provided with a tapered chamber to receive I the adjustable tapered plug 2, and the other end is internally screw-threaded to receivethe corresponding screw-threaded end of the hydrogen or Rigidly secured within the end of the hydrogen or acetylene-gas supply pipe 3, is an apertured disk 4:, the face of which is provided with a series of gas conveying grooves or passages 5 extending across the entire face thereof. The adjustable tapered plug 2 is provided with a longitudinally arranged bore which is in alinement with the aperture of the disk 4: and through which the oxygen 1 supply pipe 6 passes said oxygen supplyol mpr r me i cutting and welding torches for cutting and, welding metals by means of a flame 'produc ed by the ignition of two gases, near thepoint-of the obj ect being'to' provide in acetylene-gas supply pipe 3.

. ItQwill thus be seen hat'a'supply v the oxygenfsupply pipe dextends from theivery'beginning of 8O throughthe handle 8 in Which it rigidly secured.

One end of the hydrogen oracetylene-gas supplypipe 3 is screw threaded andv has 1 screw-threaded engagement with a screwthreaded cavity 9 formed in the handle 8,

through which the oxygen supply-pipe '6 also passes.

I The handle 8 is further provided with ex.

tended screw threaded nipples, lOand 11 each of which is designed to connect respece t-ively with sources of supply of acetylene and oxygen by any suitable andv desired means,

Secured to a shouldered portion of the handle 8 is one end of av tube 12 preferably IllZtCle of fiber, the other end of which isse-' cured to the circular apertured member 3 in o any desired or convenient manner, through which the hydrogen or acetylene-gas supplypipe 3 passes. i The hydrogen as clearly indicated in Fig. 1 of the drawings, is packed with a finely divided pervious non-inflammable material 1 1 preferably asbestos, glass wool or the like.

This inflammable material or packing pro-' I or acetylene-gas supply- ;v

vides arestricted passage way for-the gas and also minimizes the danger of the"propagation of theflame through thegas.

It will, of course, be understood that though I prefer to use acetylene and oxygen in my torch, any other appropriate combus tible gas may be substituted for the acetylene, and any other appropriate gaseous supporter of combustion for the oxygen.

Experience has demonstrated-that the or-* ganization above described; is a highly efiicient one, and while I have shown the preferred embodiment of my present inventlo'n,

I do not wish to .be limited to the exact detailsfof construction shown and described, as obvious nod ficatlons thereof, not lnvolvmg theexerclse of invention, maybe made by any skilled mechanic, and such departures fromfwhat is .herein set forth, I consider within the sc'ope and terms of my claims;

Having thus described my invention, what I claim as new and desire to secure by Let tersPatent is 1+- v 1. A gas torch for cutting and welding metals, comprising a head provided with a tapered chamber, a grooved tapered plug located within said chamber, a gas supply pipe secured in the end of said head, all independent apertured 'disk provided with grooveslocated inthe end of said gas supply-pipe, and a second gas supply-pipe'of smaller diameter passing through the entire length of the first named gas supply-pipe and through said apertured disk and projectinginto the outer-most end of said tapered plug. 7

2. A gas torch" for cutting and welding metals, comprising a head provided with a tapered chamber, a tapered plug provided with grooves located within said chamber, a gas supply-pipe secured within the end of said head, and a second gas supply-pipe of smaller diameter passing through the entire length of the first named gas supply-pipe and terminating in the outermost end of said tapered plug.

3. A gas torch for cutting and welding metals, comprising a head provided with a tapered chamber, a grooved tapered plugv provided with a central longitudinal bore located within said chamber, a gas supplypipe secured in the rend of said head, an independent disk located in the end of said gas supply-pipe, said disk and plug beingprovided with registering gas passages commu-' nicating With said supply-pipe, and a second CHARLES F.
